摘　　要：针对综合管廊传统建造方式占地面积大、人力投入大、工序复杂、效率较低等不足,提出“盾构技术+架桥技术”深度融合的综合管廊“盾架一体化”建造理念,研制相应的绿色装配式综合管廊U盾架管机。首先,详细介绍U盾架管机整机设计,包括具备模块化无级可变径功能的U型移动支护盾体设计以及负责管节安装的门型双支腿单主梁高精度架管装置设计,可以适应不同断面综合管廊建设,管节拼装误差在±5mm以内;同时,还介绍了垫层摊铺系统、新型经济型管廊侧缝填充材料“速凝液态土”制备及同步填充系统设计,可以解决综合管廊垫层机械化摊铺、侧缝同步回填的难题;然后,以雄安新区某综合管廊建设项目为依托,介绍U盾架管机总体及管节拼装、垫层摊铺、侧缝填充、变径等关键技术施工应用情况,并与传统明挖现浇工法进行对比分析。应用表明,与传统工法相比,U盾架管机工法节省占地宽度44%,提升施工工效37.5%,同时在施工安全性、建设品质、经济性方面均具有明显优势。To address the limitations of traditional utility tunnel construction methods,which involve large land use,high labor input,complex processes and low efficiency,this study proposes the construction concept of"Shield+Pipe erecting"for utility tunnels,which deeply integrates the"shield tunnelling technology and bridge erecting tech⁃nology".A U-shield pipe erecting machine for green prefabricated utility tunnels was developed accordingly.The paper first provides a detailed introduction to the U-shield pipe erecting machine's overall design,including the de⁃sign of U-shaped shield with modular structure and stepless variable diameter function,which can adapt to the con⁃struction of utility tunnels with different cross-sections,and the design of high precision pipe erecting machine with a door-type double-leg single main beam,which can control the erection error of pipes within±5 mm.Additionally,the blinding layer paving system and the simultaneous filling system with new economical materials“quick-setting liquid soil”are introduced,which solves the problem of mechanized paving of blinding layer and synchronous filling of side joints.Based on the utility tunnel project in Xiong′an New Area,the application of the key technologies of the U-shaped shield pipe erecting machine such as pipe erecting,blinding layer paving,side joint filling and variable cross section adaption are introduced.Compared with traditional open-cut and cast-in-place construction method,this method saves site width by 44%,improves construction efficiency by 37.5%,and has significant advantages in terms of construction safety,quality,and cost-effectiveness.
